Re: Pi 3 SFTP very slow using onboard wireless

Wireless speed is based on signal strength. The Pi3 has a tiny chip antenna that doesn't give a lot of range so you may be too far from the Access Point, or there may be interferring signals slowing you down. Ethernet will always be the fastest way to go.

Re: Default desktop changed - how to restore original?

The easiest solution is to reformat the SD card and reload Noobs or Raspbian. It would be impossible to know what you did wrong in installng Samba so it is hard to suggest a fix. Before installing anything, be sure to do apt-get update and apt-get dist-upgrade.

Your SD cards should be tested with f3write/f3read (linux) or h2testw (windows) before formatting and installing an OS. Unfortunately, this can't be done without wiping out your existing OS and files on that SD card but at least you will know that it is not a counterfeit. Counterfeits are possible f...

Sorry...I have not used the FTDI myself but have used a USB serial adapter/voltage shifter (Adafruit USB to serial console cable) and it just worked...got directly to a login prompt just like using the cli mode. They are pretty cheap and very easy to use and can power a Pi0 from that cable directly.

Re: SD card corrupted at shutdown (no gui)

Raspi-config and the GUI config utility have a setting for the Pi to start from either the cli or GUI. I think default is the cli. Can you restart the GUI after reboot by entering

Code: Select all

startx
at the cli prompt? Check raspi-config for that setting.

If the power failure caught the Pi in the act of writing to a file, it may have corrupted the uSD card as they tend to be fragile that way. Try reformatting the card (FAT32) and reload the OS on it. They don't always reformat gracefully...you may need to write a new partition table before formatting...

The low brightness could result from having some kind of a short on the Pi2 board. If you have a DVM, carefully (not to short pins) check the voltage across pin 1 (gnd) and pin 2 or 3 (5 VDC) of the GPIO bus. That should be >4.7 VDC. If not, you may have a short.
